For most of the year, annual killifish persist as diapausing embryos buried in sediments across the African savannah. When rainwater fills small depressions across the landscape, the fish must hatch, grow, mature, and produce the next generation before the pool dries up. Researchers have found that these small fish condense their life cycle even the wild than expected based on studies in the lab.

Researchers have discovered how two brain regions work together to maintain attention, and how discordance between the regions could lead to attention deficit disorders, including schizophrenia, bipolar disorder, and major depression.

Investing in diminishing socioeconomic status inequalities and in preventing violent events during childhood may improve the mental health of youths from low socioeconomic status backgrounds. The results showed that having experienced any traumatic event and low socioeconomic status were associated with an internalizing disorder such as depression and anxiety and an externalizing disorder including attention-deficit hyperactivity.

New research illustrates the unhealthy effects racism can have on children, with reported exposure to discrimination tied to higher rates of attention deficit hyperactivity disorder (ADHD), anxiety and depression, as well as decreased general health.

Many people think of psychedelics as relics from the hippie generation or something taken by ravers and music festival-goers, but they may one day be used to treat disorders ranging from social anxiety to depression, according to new research.

Researchers suggest dysfunction in mitochondria -- the main source of energy for cells -- may be the root cause of depression. The finding brings new insight to long-held theories of the causes of depression and could lead to the development of novel and more effective antidepressant drugs.
